Reaction Steps

To a stirred solution of N-[1-methyl-5-(tritylamino)-1H-pyrazol-4-yl]-2-(tritylamino)acetamide (2 g) in N,N-dimethylformamide (20 ml) was added sodium hydride (245 mg, 60% oil suspension) at 0° C., and the mixture was stirred for 30 minutes with warming to room temperature. The mixture was cooled to 0° C., and methyl iodide (1.3 g) was added. The whole mixture was stirred at room temperature overnight. Water (5 ml) was added, and the whole mixture was extracted with ethyl acetate. The organic layer was washed with water and brine and dried over magnesium sulfate. Evaporation of the solvent under reduced pressure gave N-methyl-N-[1-methyl-5-(tritylamino)-1H-pyrazol-4-yl]-2-(tritylamino)acetamide (2.05 g).
